Abstract

A controlled covalent functionalization of multiwalled carbon nanotubes was reported through Diels-Alder cycloaddition of various substituted benzocyclobutenes and the extent of control over the functionalization at different temperatures was investigated. The quality of MWNT attached to the surfaces was determined from thermogravimetric analysis (TGA), which showed two distinct weight losses at 200 to 480 °C and the other at 590 to 625 °C. The FT-IR spectrum of various substituted MWNTs reveals characteristic vibrations of aromatic and CH modes along with the characteristic vibration modes for the substitutional group. The decomposition of MWNTs is clearly seen at 568 °C while the weight increase is attributed to the reaction of residual pendant MWNT groups of the polymer with oxygen present in the furnace.
